From dac65f99e8bf1fbe2e15fa96ef901623bb49dc89 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Tue, 26 Nov 2013 13:08:28 +0100 Subject: console: Set Linux console parameter automatically Linux specifies the linux,stdout-path property in the /chosen node in the devicetree. Unfortunately this is ignored in most cases. For cases in which barebox uses this property for its own use we translate this into a Linux boot arg with: - the console name provided by the serial driver - the the instance from the 'serial' alias - the baudrate from the actual baudrate. So with this it's for devicetee enabled boards no longer necessary to manually assign a console= parameter. Should a user not want to use the automatically assigned parameter it should do: global.linux.bootargs.console= in the environment.
